Gas/liquid mass transfer coefficients, which are crucial for estimating the design of absorption towers, can be found using wetted wall columns. These coefficients provide the foundation for the correlations that are utilized to create packed towers. This equipment investigates the uptake of oxygen into deoxygenated water (prepared by nitrogen sparing). This is an illustration of controlled liquid film absorption.. Different water mass flow rates can be used to calculate the liquid film mass transfer coefficient.
